There are photos form the station, station is modern and in reconstruction too, so big with many platforms, unfortunately again with nonsense security gates . To access platforms 1 and 2 est you can use underpassage with travelators and in half of platforms there are a connecting all platform together and is not too much used.
Waiting hall have two stories with nice view over the station from above and shopping facilities under the station and tunnel to the metro station Termini
